SHEABING-MACHINE.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed December 26, 1906. $erial No. 349,451.

To all whom it may concern:

; 4 Be it known that I, JOHN J. VALLIERE, a citizen of the United States, and a resident of Fair Oaks, in the county of Sacramento and State of California, have invented a new and Improved Shearing-Machine, of which the following is a full, clear, and exact description.

This invention relates to certain improvements in shearing machines, and the object thereof is to provide means whereby one of the cutting members is moved in a curve to a position substantially parallel to the other cutting member before the two are brought together. Thus the curved cutting member serves not only to sever the material being cut, but also serves to draw the same into the comb.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures, in which Figure 1 is a perspective view of my improved shearing machine; Fig. 2 is a section taken just below the cover plate of the machine and showing the cutting member about to begin the cutting stroke; Fig. 3 is a view similar to Fig. 2, but showing the cutting member in its outermost position; Fig. 4 is a view similar to Figs. 2 and 3, but showing the cutting member at the completion of the cutting stroke, said view being taken on the line 14 of Fig. 5; Fig. 5 is a central longitudinal section taken on the line 55 of Fig. 4; Fig. 6 is a plan view of the movable cutting member; Fig. 7 is a perspective view of the supporting arm for the movable cutting member; and Fig. 8 is a view of the stationary cutting member.

In the specific embodiment of the device which is illustrated in the accompanying drawings, my invention involves a casing having a bottom plate 1 and a removable top plate 2 parallel thereto. The bottom plate 1 carries side walls 3, upon theedges of which the top plate 2 rests. Within the casing formed by the top, bottom, and side plates is inclosed the operating mechanism deriving its power from a flexible shaft 4 or other means entering the casing at one end, while at the opposite end of the casing is located the cutting members and the comb. The comb 5 is formed of a plurality of teeth extending outward from the end of the casing and substantiallyin alinement with the bottom plate 1 thereof. These teeth may be formed either integral with the base plate 1, as shown, or they may be formed from a separate piece and secured to the bottom member 1 in any suitable manner. At the base of the teeth and at the open end of the casing is located the stationary cutting member 6, which is formed of a curved piece of metal having a flat upper surface upon which the movable cutting member rests, and having a sharp well-defined angle at its outer edge cooperating with the movable cutting member to sever the material. This member may be secured in place in any suitable manner, but is preferably provided with two countersunk screw-bolts 7 at or adjacent its ends by which it is rigidly secured to the base plate 1. The movable cutting member 8 is curved in the arc of a circle and its outer end is brought to a very sharp point 9. One side of this cutting member is preferably flat and is adapted to slide over the stationary cutting member, while the upper surface is beveled so as to present a sharp cutting edge 10. The cutting member 8 is secured to and carried by an arm 11, pivoted within the casing and of a length substantially equal to the radius of a circle in the circumference of which the curved cutting member 8would lie.

The bottom and top plates 1 and 2 are secured together by a screw-bolt 12 which extends through an opening in the end of the arm 11 and serves as a pivot pin for said arm. A portion 13 of the arm around this opening is of a thickness substantially equal to the distance between the inner and outer plates, so as to hold the cutting member from movement other than in the same plane, while the remaining portion of the arm is of any desired thickness. The opening 14 through which the pivot pin 12 extends is elongated so as to permit a lateral movement of the arm 11 and the curved cutting member. The cutting member is secured to the outer end of the arm 11 in any suitable manner, preferably by being inserted through an opening 15 in the arm and secured therein by a screw 16 passing through the edge of the cutting member. The pivoted end of the arm 11 is provided with a projection 17 to which is pivoted the operating pitman 18, the opposite end of which is pivoted adjacent the circumference of a wheel 19 carried by the main drive shaft 4. The length of the projection 17 is considerably less than the distance from the center of the wheel 19 to the point at which the pitman 18 is secured, while the slot 14 in the inner end of the arm is substantially equal to said distance. Within the casing and pivoted to the side walls 3 are two springs 20 and 21 which bear against the pitman 18 and control its lateral movement.

For guiding the machine while in operation I preferably provide a finger 22, having one side extending parallel with the teeth of the comb, and having the other side curving outward and forming a portion of the side wall 3. This finger serves to press the material which is not in the path of the comb toward one side and out of the way, so that a straight out may be made. The outer tooth at the opposite end of the comb is in alinement with the side of the machine, so that the operator may cut as close as desired upon any angular surface.

In the employment of my improved shearing machine the shaft 4 is connected to any suitable source of power and continuously rotated in the direction indicated by the arrow in Figs. 2, 3 and 4. Starting with the parts in the position shown in Fig. 2, the spring 21 bears against the pitman 18 and forces the arm 11 to the position shown, namely, with the pivot pin 12 at the inner end of the slot 14. As the wheel 19 rotates to the position shown in Fig. 3, the spring 21 maintains the pivot pin 12 and the slot 14 in the same relative position, while the longitudinal movement of the pitman causes the curved cutting member to swing around into the position shown in Fig. 3. 'In this position the projection 17 and the pitman 18 are very nearly in alinement, but the pitman 18 extends substantially at right angles to a line through the shaft 4 and the point of connection between said pitman and the wheel 19. Upon further rotation of the wheel 19, it is evident that the pitman 18 is drawn still further toward the end of the casing, and as the projection 17 is not long enough to fully accommodate for this movement, the arm 11 is moved in a lateral direction to the position indicated in Fig. 4, in which the pivot pin 12 is at the outer end of the slot 14. This movement causes the curved cutting member to be drawn in toward the stationary cutting member and causes the severing oi the material projecting through the comb and between the cutting members. As the pitman 18 passes the dead. centerof the wheel 19, it is brought out of engagement with the spring 21 and into engagement with the spring 20, so that further movement causes the simultaneous withdrawal of the curved cutting memher 8 into the casing and the forcing of the pivot pin 12 to the inner end of the cutting member, to the position shown in Fig. 2, from which position the motion above described is repeated. The spring 20 prevents the projection 17 and the pitman 18 from passing beyond the line of centers through the shaft 4 and the pivot pin 12, so that as soon as the pivotal point of the pitman 18 and wheel 19 passes the center from the po sition shown in Fig. 4, the spring 20 prevents the cutting device from iru'ther rotation around the pivot pin 12 and causes it to be withdrawn into the casing.

The operating mechanism above described serves to give the movable cutting blade 8 a motion similar to the swinging of a sickle. The blade moves first around the arc of a circle and then is drawn in toward the center of the circle and in engagement with the stationary cutting member 6, whereby the material is severed. The lower or stationary cutting member 6 is supported upon the base plate 1, and the vertical front edge which it presents is of a suflicient height to prevent the flesh which may rise slightly between the teeth of the comb, from coming into engagement with the edges of the cutting members.

The device is very simple in its operation and very eflicient in the shearing of animals of various kinds, as,

for instance, sheep, horses, goats, and the like.

Various changes may be made in the specific details of the machine without departing from the spirit of my invention.

Havlng thus descrlbed my 1nvention, I claim as new and desire to secure by Letters Patent:
